Here’s what Ehrman says in an interview found in the appendix of Misquoting Jesus (p. 252):

Bruce Metzger is one of the great scholars of modern times, and I dedicated the book to him because he was both my inspiration for going into textual criticism and the person who trained me in the field. I have nothing but respect and admiration for him. And even though we may disagree on important religious questions – he is a firmly committed Christian and I am not – we are in complete agreement on a number of very important historical and textual questions. If he and I were put in a room and asked to hammer out a consensus statement on what we think the original text of the New Testament probably looked like, there would be very few points of disagreement – maybe one or two dozen places out of many thousands. The position I argue for in ‘Misquoting Jesus’ does not actually stand at odds with Prof. Metzger’s position that the essential Christian beliefs are not affected by textual variants in the manuscript tradition of the New Testament.
